Designed for studio art instructors, museum education programs, public libraries, high school teachers, and those who buy slides for teaching art history at the college level, this guide lists sources of slides in the United States and over 20 foreign countries. All U.S. sources are listed first, commercial sources are alphabetical by name and country, then museums alphabetical by city, followed by institutional sources. Evaluations are verbal instead of statistical. Questionnaires sent to slide suppliers provided the primary source of information. A list of sources for slide mounting materials has been added.
